"I hired Capital City Handyman Services for just a few small things in my cabin. Plumbing was a big issue and he replaced all the pipes that that were old and cracked. Then he built a retainer wall for my basement and insulated and winterized it as well. All of this was done in a timely matter. He was thorough, clean, and perfesional. He also installed flooring, and put in a new kitchen sink. I give Capital City Handyman an A plus. Well done! He also trimmed my trees!"

Drywall FAQs, answered by experts

While a normal moisture level for drywall is between 5% and 12%, replacement is recommended if you get consistent readings above 17%. At this level, the drywall is likely too compromised by extensive moisture damage to be considered safe. You can replace either the entire sheet or just the affected section. If you are unsure after a visual inspection, it is best to have a contractor or water restoration provider use a professional moisture meter to get an accurate reading.

Most drywall used for interior walls of homes is 1/2-inch thick. This size strikes a balance of being easy to handle and hang while being thick enough for the durability needed on interior wall applications.

If your home’s foundation shifts slightly over time, any seams in the drywall represent the weakest point in the wall, leading to cracks. If your home has significant changes in temperature and humidity, this can cause the drywall to swell and contract slightly, causing a crack at the weak point of the seam. If your drywall installer did a poor job securing the panels to the wall studs, this could cause a weak layout and cracks in the seams.

Yes, you can apply new plaster over an existing plaster surface, such as a wall or ceiling, provided the old plaster is in good condition. Before you begin, check the stability of the existing plaster. The surface must be clean, free of loose material, and have no peeling paint. It is also recommended to roughen the surface slightly to promote adhesion. For older plaster, applying a base coat like a PVA emulsion or a specific bonding agent or primer is crucial. This step makes the existing plaster less porous and ensures the new and old layers adhere properly for a smooth, long-lasting finish.

Plastering lasts for around 15 to 20 years without needing repairs or maintenance in most cases, and with proper upkeep, plastering can last a lifetime—sometimes more than 100 years. Plaster repair costs between $1 and $3 per square foot, and you may need these services once every 15 to 20 years or so unless you have a harsh climate where humidity changes are a constant issue. You can also opt to skim-coat plaster for between $0.90 and $1.30 per square foot, which may serve you better in the long run.
